INSTALLATION – ASSEMBLY INSTRUCTIONS

During the installation of the accessory please use adequate Personal Protective Equipment: gloves, safety shoes, helmet, etc. Thimbles are used to form eyes of metal wire ropes for use in anchoring and pulling. The goal is to prevent wire ropes from getting deformed and worn as the result of loads and friction with other parts. Fit the thimble into the eye end of the metal wire rope. Apply the first wire rope clip at a distance equalling its width from the dead end of the wire rope (Fig. 1). The end part of the wire rope should be at least as long as shown in “Table A” (T value); in addition, the end of the wire rope should be bound up .

Fig. 1

Apply the threaded U-bolt to the end part of the wire rope (dead end); the active part of the wire rope – that is, the pulling one – is supported by the body of the wire rope clip. Tighten the nuts uniformly, alternating torque application.

Fit the wire rope into the thimble seat perfectly, and apply the second wire rope clip as near as possible to it, locking the nuts firmly, without tightening them (Fig. 2).

Fig. 2

The other wire rope clips should be mounted between the first and second clips, at a distance which exceeds or is equal to their S-width from each other (Fig. 3).

Fig. 3

Tighten in such a way as to avoid creating folds or loose parts in the wire rope; then tighten the nuts of each threaded U-bolt uniformly, alternating from one nut to the other, until the recommended torque is reached.

8) USING ACCESSORY – GRIP AND HANDLING

Apply the first load to test the unit. Then check the unit and retighten the nuts to the recommended torque. Periodically check tensile stress, the state of preservation of the parts and their connection, according to the Table “Maintenance jobs and inspections”.
